The highly efficient asymmetric hydrogenation of alpha-arylmethylene cycloalkanones catalyzed by Ir-complexes of chiral spiro aminophosphine ligands was developed, providing chiral exo-cyclic allylic alcohols at high yields with excellent enantioselectivities (up to 97% ee) and high turnover numbers (S/C up to 10,000). This new reaction provided an efficient method for the synthesis of the key intermediate
开发了由手性螺氨基膦配体的 Ir 配合物催化的 α-芳基亚甲基环烷酮的高效不对称氢化,以高产率提供手性外环烯丙醇,具有优异的对映选择性(高达 97% ee)和高转换数(S/ C 高达 10,000)。这一新反应为合成抗炎洛索洛芬活性形式的关键中间体提供了一种有效的方法。
